ROBERT RUDDY, OF MOUNT VERNON, NEW YORK, ASSIGNOR TO NATHAN MANUFACTURING COMPANY, OF NEW YORK, N. Y.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No.316,834, dated Apri128, 1885.

Application filed March E), 1885. (No model.)

T alt whom, t may concern,.-

Be it known that I, ROBERT BUDDY, of Mount Vernon, Testchester county, New

York, have invented certain new and useful Improvements in Lnbricators, of which the following is a specification.

My invention is directed to lubricators intended inore particularly for use with locomotives, and refers to that class of lubricators known as drop-feed lubricators,77 in which water resulting from the condensation of steam is used for the purpose of raising the oil to a certain height in the cup, whence said oil will be carried off through a sight-feed tube or glass into the steam-conduit, and thence to the parts to be lubricated.

My object is to simplify, as far as possible, the construction and arrangement of the parts, while maintaining the entire efficiency of the lnbricator.

The nature of my improvements can best be explained and understoodby reference to the accompanying drawings, in whicl1- Figure l is a vertical central section of the lubricator on line 1 l, Fig. 3. Fig. 2 is a like section on line 2 2, Fig. 3.A Fig. 3 is a horizontal section of the oil-cup on line 3 3, Fig. 1, omitting the sight-feedtube connections and the valve for controlling the escape of the water from the condensing-chamber into the oil-cup.

The oil cup or receptacle is represented at F. It is cast in one with a tubular neck, A, constituting the main steam-conduit, and with a horizontal channel, D, forming a continuation of that conduit, which is cast upon the bottoni of the lubricator and leads into the lower connection, O, of the sight-feed tube or glass E. This construction of parts is simple and effective, aiiordng opportunity also for the ready application of the pipe B, which supplies steam from the conduit Ato the condensing-chamber G. This chamber is above the oil-cup, and is screwed to a neck on top of 45 the same, as shown, the cup and chamber being separated by a packing-nut, G, through which the steam-pipe B passes. The steampipe screws 'into the bottom of the oil-cup and opens into the steam-conduit at the junction 5o of A and D. It thence extends upthrough the oil-cup, passes through the" packing-nut G, (with which it makes tight joint,) and terminates inthe upper part of condensing-chamber. The packingnut prevents the water from leaking from the condensing-chamberr into the oil-cup, and at the same time is a guide and support for the steampipe B. By means of this construction only a single straight connection is required between the main steamchannel A D below the oil-cup 63 and the condensingfchainber above the oilcup, and this connection is through the cup it self', thus avoiding` the usual pipe-connections,

' which require additional space, couplings, Ste.

In the top of the oilcup is cast the double 6 5 chamber H J, the former, H, opening into the bottom of the condensingchamber through the neck to which said chamber is screwed, and the latter, J,having a bottom opening, into which is screwed a pipe, L, which eX- tends down to or nearly to the bottom of the lubricator. Through the parts H J L the water of condensation is fed to the oil-cup from the condensing-chamber.

The rate of feed is governed by a valve on the end of a valve-spindle, K, which extends laterally from the oil-cup. The seat for the valve is formed at the point where the cham bers H J join one another, as seen in Fig'. l.

I prefer that the lower end of the water-feed 8o pipe L should extend down into a pocket,

Il., the bottom of which is below the level of the lowest point in the oil-cup. By this ar'- rangement I provide a water-packing at the outlet of pipe L, and consequently the oil, be- 8 5 ing lighter than water, can never enter the water-pipe L. A convenient way of providing the pocket is to form it in the inner end of a plug, M, which screws into an opening formed for it at an appropriate point in the 9o bottom of the oil-cup.

The sight'feed glass or tube E, which is eX- ternal to the oil-cup, is held by and between the lower connection, O, hereinbefore referred to, and an upper connection, l?, provided with an inlet, N, which opens into the oilcup at or near the top. This upper connection is provided with a nipple or nozzle, g, for the oil to drop from, and with a valve, h, to control the oil-feed.

Steam from the main steam-conduit passes through pipe B into the condensing-chamber,

-located within the body and at the same time through Channel D directly into the sight-feed glass or tube E. By this construction and arrangement no separate pipe-connections are required to conduct the steam into the sight-feed deviee.

The lubrieator is of course provided, as usual, with a valve, S, to control the steamsupply, with a 'waste or draw-off cock, T, and with a lling-plug, R.

Having described iny improvements, what I claim herein as new and of my own invention is as follows:

1. The combination, with the oil-cup, the sight-feed glass, and its connections, of the main steam-conduit A and the channel D, of the oil-cup, and extending upon the bottoni of the same from the main steanreonduit to the lower sight` feed connection, said parts being east in one with the cup, as herenbefore set forth.

2. The oil-cup formed with a neck to receive the condensing chamber or bulb C, said neck having an opening for the passage ofthe steam-pipe, in combination with the main steam-eonduit A, the steam-pipe leading from said conduit up through the opening in the n'eek of the oil-cup into the condensing-chamber, and the packing nut or gland G, itted to said opening and around the -said steampipe above the outside of the oil-chamber, as hereinbefore set forth.

3. The oil-cup, the sight-feed glass and its connections, and the condensing-chamber, in combination with the steam-Conduit A and channel D, east in one with the eup, the steampipe B, extending from the said steam-conduit up into the eondensing-ehamber through an opening in the top of the oil-Cup, and the- ROBERT BUDDY.
